In this study, a steady-state heterogeneous onedimensional
model predicts the performance of a thermally
double coupled auto-thermal multi-tubular reactor
for simultaneous production of hydrogen, benzene,
methanol and dimethyether (DME) in an economical
approach for both co- and counter- current modes of
operation. Reversed flow of cyclohexane has been considered
for the counter-current flow regime. The simulation
results for co- and counter-current modes have been
investigated and compared with corresponding predictions
for conventional methanol reactor and traditional
coupled methanol reactor. In addition, various operating
parameters along the reactor have been studied. The
simulation results present that methanol yield in coand
counter- current modes are reached to 0.3735 and
0.3363 in a thermally double coupled reactor, respectively.
Also, results for counter-current mode show a
superior performance in hydrogen and benzene production.
Finally, the results of simulation illustrate that the
coupling of these reactions could be beneficial.
